I've also had good results with both ZoTwist and SPPP 1.28/Sweet 16 in the fan-pattern Ti S6 style racquets.
Intellistring, Intellitour, and the whole RIP Family work great in those, as well.

Most of those people were ill-advised and bought the wrong racquet.

"No, Dammit, I'll make it work if it's the last thing I do. Maybe a better string?"

"Ok, yes, there is a better string for you."
"We'll make it work (whisper- But you really should be thinking about a different racquet).
"Oh, man! I love the lightness of this racquet!"
"Okay, you got it, RedCode 1.30/Leoina66, it is."
